Spikingformer: Spike-driven Residual Learning for Transformer-based Spiking Neural Network, Arxiv 2023

Spikingformer is a pure event-driven transformer-based spiking neural network (75.85% top-1 accuracy on ImageNet-1K, + 1.04% and significantly reduces energy consumption by 57.34% compared with Spikformer). To our best knowledge, this is the first time that a pure event-driven transformer-based SNN has been developed in 2023/04.

News

[2024.2.23] Update energy_consumption_calculation of Spikingformer or Spikformer on ImageNet.

[2023.9.11] Update origin_logs and cifar10 trained model.

[2023.8.18] Update trained models.

A Handwriting Error Correction in Manuscript

In neuromorphic datasets, the preprocessing (transforming events into frames) of neuromorphic datasets is according to SEW or SpikingJelly. The event stream comprises four dimensions: the event’s coordinate (x, y), time (t), and polarity (p). We split the event’s number N into T (the simulating time-step) slices with nearly the same number of events in each slice and integrate events into frames. It is a pity that Equation 20 in the manuscript is a formula mistake, we corrected it as follows: $$E_{Spikingformer}^{neuro}=E_{A C} \times\left(\sum_{i=2}^N S O P_{{Conv} }^i+\sum_{j=1}^M S O P_{{SSA}}^j\right)+E_{M A C} \times\left(FLOP_{{Conv}}^1\right)$$
